It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs, all payable per-request via the x402 protocol on the Base network using USDC.\n\nThe specific endpoint `/api/v1/database/snapshots/2025-07` accepts POST requests and returns JSON. The x402 challenge indicates a maximum cost of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). The platform advertises uniform $0.02/request pricing across all endpoints, with no API keys, no rate limits, and no minimum commitments required.\n\nDocumentation is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no usage examples available. The endpoint name suggests it returns a monthly database snapshot, but the exact contents, schema, and supported query parameters are unknown. The endpoint is confirmed live via a valid 402 challenge response.","tags":[],"capabilities":["database-snapshot","x402-payment","usdc-settlement","base-network","per-request-pricing","json-response"],"categories":["data","storage"],"synonyms":["database export","monthly snapshot","data dump","database backup","data snapshot API","lowpaymentfee"],"warnings":["No documentation available — /docs, /api, /pricing, and /README all return only a 'Connect wallet' prompt with no technical content.","No OpenAPI or schema definition found; request body format and response structure are unknown.","The exact contents and structure of the 'database snapshot' are undocumented — buyers cannot know what they are paying for before purchasing.","No robots.txt or agents.txt present on the origin."],"endpointUrl":"https://lowpaymentfee.com/api/v1/database/snapshots/2025-07","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/database/snapshots/2025-07","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02/request in USDC on Base).
